  description: '[Deltares](https://www.deltares.nl/en/) has produced a hydrological
    model approach to simulate historical daily reservoir variations for 3,236 locations
    across the globe for the period 1970-2020 using the distributed [wflow_sbm](https://deltares.github.io/Wflow.jl/stable/model_docs/model_configurations/)
    model. The model outputs long-term daily information on reservoir volume, inflow
    and outflow dynamics, as well as information on upstream hydrological forcing.


    They hydrological model was forced with 5 different precipitation products. Two
    products (ERA5 and CHIRPS) are available at the global scale, while for Europe,
    USA and Australia a regional product was use (i.e. EOBS, NLDAS and BOM, respectively).
    Using these different precipitation products, it becomes possible to assess the
    impact of uncertainty in the model forcing. A different number of basins upstream
    of reservoirs are simulated, given the spatial coverage of each precipitation
    product.
